GreBul: The Cycle Repeats
Heracles straightened up, the bouquet sitting in front of the tombstone. This was the only problem with being immortal: having to bury the lovers he outlived.
But he knew that he would see him again in fifty years. That was part of the curse: Heracles lived forever, and Dimitros was reincarnated. Their paths would inevitably cross again in fifty years, and they would have ten years together before misfortune stole Dimitros, or whatever the name of his current incarnation was.
Heracles had fifty years to do what he always did when he was waiting: find a way to undo the curse.
He stared at the tombstone for a moment longer before he turned away. It wasn't the first grave, and unless he managed to find a way to undo the curse, it wouldn't be the last.
…
Heracles was wandering through the streets of Sofia. His latest lead had brought him to Bulgaria, but he was also looking for something else: It had already been fifty years since the last incarnation of his lover had died.
He sensed something behind him and spun around, forcing the person walking behind him to slam into him. He instinctively wrapped him in his arms.
When the man looked up, Heracles immediately recognised the green eyes and black hair. And for a while, the expression was blank, before the smaller male recognised him. At least one small mercy was that he would remember his past lives, and more importantly, he would remember Heracles.
"Hera?" the shorter male asked.
Heracles smiled.
"Dimitros," he said.
The other smiled.
"It's Dimitri now," he said.
"Dimitri…" Heracles said. "Close enough."
And as they would usually do upon their reunion, the two made their way to the nearest café to catch up on all that had happened in the last fifty years, though Dimitri only had twenty-five years to share.
The prompt is: 'Imagine that person A of your OTP is immortal while person B is mortal but reincarnates.'
